<dt>Headstock Angle</dt>
<dd>The angle at which the head is tilted back from the neck plane. A shallow angle may to a small amount affect the tendency to create string buzz when heavily plucked. The steepness of the back angle  in the nut, according to <a href="http://www.cumpiano.com/Home/Newsletters/Issues/newsletter%2020.htm#Headstock angle">Cumpiano's newsletter 20</a>, defines the "vector of tension forces". There also may be an effect on feel and sound. A more shallow angle also increases the gluing area, which is good.</dd>
